Knob [1]
EG1 Int1 (EG1 Intensity/Filter1) [–63...63]
This specifies how time-variant modula-
tion from the EG1 will be applied to the
cutoff frequency (☞Figure 9-1). The cutoff
frequency will change over time according
to the EG1 settings, modifying the tone. For
example, you can use this to create a sound
that gradually begins to brighten when you
press the key, and then gradually becomes
darker.
"EG1 Int1" parameter specifies the depth
(sensitivity) to which the EG1 will affect
the cutoff frequency.
With a setting of 0, the EG1 will not affect
the cutoff frequency.
Increasingly positive (+) settings will allow
the EG1 to have a correspondingly greater
effect on the cutoff frequency (☞Figure 9-2).
Increasingly negative (-) settings will allow
a correspondingly greater effect in the op-
posite direction (☞Figure 9-3).

Here you can set the values of the filter 1 parameters.
Knob [2]
Key Trk1 (Keyboard Tracking/Filter1)
This specifies how keyboard tracking (the
keyboard location that you play) will affect
the cutoff frequency. For example if the
sound played by the C4 key has the desired
tone but higher notes no longer have reso-
nance or are too mellow-sounding, you can
adjust keyboard tracking to make compen-
sations so that the cutoff frequency will rise
for higher notes.
With positive (+) settings, the cutoff frequency
will rise as you play upward from the C4 note,
and fall as you play downward.
With negative (-) settings, the cutoff frequency
will fall as you play upward from the C4 note,
and rise as you play downward.
With a setting of +48, the change in
cutoff frequency will be proportionate
to the change in pitch. With a setting
(➚)
of 0, keyboard tracking will not affect
the cutoff frequency.
Keyboard Track operates according to
the pitch that is controlled by pitch
bend, and transpose. It is not affected
by pitch changes produced by vibrato
or Virtual Patch.
Knob [3]
VelSens1 (Velocity Sensitivity/Filter1)
[–2.00...+2.00]
Specifies how velocity (keyboard playing
dynamics) will affect the cutoff frequency.
Positive (+) values will cause the cutoff fre-
quency to rise as you play more strongly.
Negative (-) values will cause the cutoff
frequency to fall as you play more strongly.
